fizixgeek: Sometimes I go through a masters' game and don't know what' going on. This is an example.
7 ... Nd7? Black has blocked in his queen bishop. Why not Bd7? Is he really so worried about his QB pawn? I guess now that he's set up his K-side fianchetto he doesn't want to rely on his king bishop to protect his QB pawn.
8 ... h6 was a question at first. Now I see that after 9. h5, this move allows 9... g5.
11. c4? e5? What's going on here? White increases the scope of Black's K bishop and invites Nb6. Black immediately blocks his own bishop and puts a big hole at d5.
I suppose with 29. ...Nxc4, Black gets three pawns for his knight, but to do so he has to allow the exchange of the rooks which at that point seems nice for White.
36. Kd2? What's White afraid of?
Then, after move 41, Black resigns!? I realize he's down a knight, but Black has the only passed pawn on the board and it seems like 41. ... Bh6 ties the White pieces up fairly well. After 42. Kd3 Qd7+ 43. Kc2 Qa4+, White almost seems in danger of drawing by perpetual check or giving up either his c-pawn or his bishop. After 42. Kf3 Qf5+ 43. Kg2 Qg4+ 44. Kf1 Qh3+ 45. Ke2 Qe6, we're right back where we started. How does White win here?
